'Partnership'

She says: "With a seat for everyone at the table there will be plenty of areas where we will be able to pool and share solutions and creativity in a strong partnership of equals, which, within a generation, I am sure, will include an independent Wales.

"Instead of clinging to the straitjacket of the single state it's time we all began to embrace this future Britain, a neighbourhood of nations, sovereign, democratic and free."

Plaid committed to achieving independence for Wales last year and Ms Wood ran under a banner of "real independence" during the Plaid leadership election.
